+description: The AP template building pipeline specialized for DECam
+# This pipeline assumes the working repo has raws, calibs, refcats, and a skymap.
+# An example of running it:
+  # pipetask run -j 4
+  #              -b REPO
+  #              -d "exposure IN (289409, 289697, 288935)"
+  #              -i DECam/raw/all,DECam/calib,DECam/calib/DM-26971,refcats/gen2,skymaps
+  #              -o DECam/templates/test1
+  #              -p APTemplate.yaml --register-dataset-types
